AMD's New Piledriver Opterons Claim to Match Intel's Performance at Half the Price

Servers are where thread-friendly new architecture shines the brightest
Today, Advanced Micro Devices, Inc. (
the Opteron 6300 Series, code-named
. Equipped with a
core, the new chips serve as an enhanced replacement to the
-equipped Opteron 6200 Series
(which was code-named
As we mentioned in our piece on the
, the new core is impressive, featuring a number of performance enhancements. However, consumer workloads tend to be lightly threaded, so the consumer workloads tend to fall short on the price-v-performance scale.
In the server market it's a very different tail. Workloads here tend to be heavily threaded in many cases, such as virtualized infrastructures, web hosting, mobile device data serving, etc.
AMD's numbers may be a bit biased, but it's claiming to essentially match rival Intel Corp.'s (
) performance in HPC (high-performance computing) applications, such as chemical simulations, with a chip that's only half the cost.
Intel will likely respond with some aggressive price cuts to stay competitive, but for now it's faced with the puzzle of how to compete with a foe that offers twice as many cores at half the cost.

Unlike the consumer market, Intel and AMD are largely competing on the same node -- 32 nm -- for server chips. This is because Intel has yet to announce E5 series chips
, having only announced E3 series dual- and quad-core offerings.
We spoke with Michael Detwiler, AMD’s Server Product Marketing Manager, who says that AMD's focus it to be "real targeted, instead of trying to be everything to everybody."
He argues that AMD's new Opterons provide "more computations per dollar" than Intel's mixed 32 nm and 22 nm Xeon line.

The chips feature a number of subtle improvements, including better branch prediction, new instruction set support, and a more efficient cache. In other words, everything is looking good, although third-party benchmarks weren't available at launch.

RE: The Opteron 6300's should sell well

The price vs performance for FX-8350 is controversial. It does well when applications are multi-threaded. Then it does not do well when applications are single threaded. Also it does not show well for power consumption vs its performance. It is hard to tell if this processor has performance vs price compared to Intel. Intel has excellent performance vs price across the board while FX-8350 hits the target sparingly and is scatter-brain for other programs.
The latest Opteron may seem cheaper than Xeon, but only if data centers are still using Opteron systems. If not, switching will be costly, so that $1000 difference will even out to be as costly as Xeon systems. Then there is evil power consumption that data centers have to figure in if going with Opteron is a better buy.
BTW, I see you camping over at dailytech instead of...xbitlabs...or...anandtech.
